Getting crashes when shutting down.

[Andreas Pakulat]

Hi,

all I did was opening kdevelop, opening quick-open, cancelling quickopen
shutting down kdevelop and it crashes when trying to access a global static
which was already deleted:

This happened the 3 times I started kdev4 today, didn't start kdev4 since
the weekend before that.
